## How to Make a Shunt Current Sense Resistor

Hi, I want to make a *beep* I said shunt! I want to make a *shunt* current sense resistor. Basically the way we measure current is by converting it into voltage passing it through a known resistor which we call a shunt and so the current is the measured voltage divided by the known resistance. […]

## How to protect circuits from reversed voltage polarity!

In this video I’m going to show you a couple of ways to protect your circuits from backwards power connections. Let’s say you have a 12 volt power source like a battery and you want to power something. It doesn’t matter what it is. Let’s say it draws 2 amperes. When the battery is connected […]

## Why 3 Phase AC instead of Single Phase???

Hi. In my last video, I talked about how Tesla won the AC-DC battle against Edison. But then he shoved three-phase AC down our throats instead of single-phase AC. Edison: “Oh no, he didn’t. He always asked for too much” Ah, get lost Eddy! Obviously Tesla had a good reason. What is a three-phase AC? […]

## Easiest MOT Salvage Tutorial Pt.2

Welcome to Part 2 of my tutorial series on MOT salvaging, where I show you how easy it is to turn a broken microwave into some cool projects. If you’ve just stumbled across this video, go watch part one first, it explains how to get a microwave oven transformer and tear it down the easiest […]

## Why Use AC Instead of DC at Home??

Hi. Why do we ever use AC to power homes instead of DC? Haven’t I showed you that AC is typically more dangerous than DC? [Painful Gurgle] Can we run everything on DC? Yes! In fact pretty much every device at home has to rectify AC into DC first before it can use it so […]

## Battery Spot Welder (CD Welder) || DIY or Buy

In a previous project video I showed you how to create a battery pack out of 18650 lithium ion batteries. Back, then I utilized a rather riskier and not recommended methods of connecting the battery cells together. By soldering the nickel strips directly to them. This can be dangerous because you heat up the battery […]

## Transistor / MOSFET tutorial

In this tutorial I’m going to go over the basics of a popular transistor and show you how you can use it to control different gadgets. What is a transistor? A transistor is a device that allows you to use small changes in voltage to switch things on and off. They are kind of like […]

## Diode Tutorial & How to build an AC to DC power supply

In this tutorial, I’m going to cover silicon diodes, bridge rectifiers, and how you convert AC to DC. Here’s the schematic symbol of a diode and a picture of the real thing. The little stripe on the end of the diode tells you which way to put it in your circuit But what is a […]
